1969 Pontiac Grand Prix Original-Owner Rapid Rarity

Interior
The '69 Grand Prix's cockpit styling was an industry first. A floor-mounted shifter was standard, and while a three-speed manual trans was standard equipment on the J, the SJ package required an M40 Turbo 400 automatic, or M20 or M21 Muncie four-speed-all subsequently added $227 to the price tag. Butch wanted a four-speed, but opted for the automatic at the salesmen's urging for improved resale value. The Custom Sport steering wheel was an option, and the Dixco tach was added.
Front Seats
Morrokide bucket seats with knit vinyl inserts and a center console were standard Grand Prix features that year. A combination of cloth and vinyl, or Custom Trim featuring leather seating was available.
Switches
The U84 reverb speaker was a $52 option controlled by a dash-mounted switch.
Original Radio
In an attempt to keep costs down, Butch opted for a U63 AM radio when placing his order, knowing that he'd add an aftermarket unit later. This Ranger eight-track unit from Tenna was installed shortly after taking delivery.
Spare Tire
The trunk was rarely used and remains in flawless condition today. The spare tire has never been removed.
Grand Prix
While the 400 four-barrel was standard on the Model J, the Y97 SJ package retailed for $244 and included a 370-horse 428ci engine. It also added an underhood lamp, cornering lamps, Rally gauge cluster, automatic level control, and specific exterior and interior identification.
Engine
Adding $119 to the cost of the SJ package, the 428 H.O. boasts a 4-bolt main block with a 4.09-inch bore, a 4-inch stroke crankshaft, No. 62 cylinder head castings yielding 10.75:1 compression, long-branch exhaust manifolds connected to a 2.25-inch dual exhaust system, and a chromed air cleaner lid, valve covers, and oil fill cap. It was gross-rated at 390 hp at 5,200 rpm and 465 lb-ft at 3,400 rpm. The XG-code engine was specific to automatic transmission applications and featured a No. 067 camshaft with 273/289-degrees of duration. A total of just 986 '69 Grand Prixs were built with the 428 H.O. backed by a Turbo 400.
Carburetor
The original No. 7029268 Rochester Quadrajet carburetor is mounted atop a typical No. 9794234 cast-iron four-barrel intake manifold. Its original No. 1111946 points-type distributor was treated to a NAPA Gold-series contact set and canister-type coil shortly after purchase. Air conditioning was only available when combining the 428 H.O. with an automatic trans. The disconnected ground wire attaches to a carb stud when the air cleaner is installed, and the yellow paint on the vacuum break was applied by the owner.
Pump
This pump mounted on the passenger side of the core support is part of the G67 Automatic Level Control. Though it was included in the SJ package, it was otherwise a $78 option. It features adjustable rear shock absorbers that maintained ride height when heavily loaded.
